VEHICLE WHEEL.

Application filed November 17, 1926, Serial No.

This invention relates to wheels for vehicles of the type described in my United States patent specification No. 1,466,550 dated August 28, 1923. This prior specification describes a disc wheel resiliently suspended trom a tubular steel ring or hoop embedded in the tyre.

The wheel according to the present invention consists of a rigid central portion resiliently suspended by an india rubber annulus from an exposed rigid tubular steel hoop around which a tyre is adapted to be mounted; The exposure of the tubular steel hoop readily permits a detachable and renewal band tyre being employed.

The india rubber annulus, like the tyre which enclosed the tubular steel hoop described in the prior specificatiomhas a cavity which permits mutual approach of the inwardly directed side ot the tubular steel hoop and the rigid central portion 01 the wheel, unhindered except for the resulting compression of the side walls of the rubber annulus.

Preferably, but not necessarily, the rigid central portion of the wheel is built up of a pair of metal discs, separated by distance sleeves and at the periphery en'ibracingthe inner border of the rubber annulus and suspended therefrom by distance pieces of triangular or other section separating the discs and. passing through the rubber.

The tubular steel hoop is preferably of box section being built up o'li' sheet steel annular side plates of channel section, welded brazed or otherwise secured to inner and outer cylindrical peripheral hoops oft sheet steel. i

The connection of the outer periphery of the rubber annulus to the inner peripheral portion of the tubular steel hoop is effected by a coinbiinition oi surjtace adhesion, interlocking, and moulding around the flanges of the lateral channel members of the hoop, which. latter is enclosed together with the rubber in a mould in which the rubberis vul- 'anized.

The tyre is preferably a band tyre moulded on to two laterally separated built-up i'netal. bands which are mounted and secured around. the outer periphery of the tubular steel hoop. y

In the accompanying drawings Fig. 1, is an axial section transverse to the plane of the wheel of a portion of the wheel eXtending from the hub to the periphery.

148,979, and in Great Britain December 5, 1925.

Figs. 2 and 3 show details.

The central portion of the wheel is built up of two stamped sheet metal discs at separated adjacent to the hub by tubular distance pieces Z) and near the periphery by distance blocks 0, arranged at intervals.

The two discs o are held together by bolts cl passing through the distance blocks 0. The metal of the discs a is stamped and plunged to form flanges around apertures fitting in shouldered recesses in the ends of the tubular distance pieces I) and thus hold these latter in place inabsence of bolts passing therethrough.

The out-er peripheral portions of the two discs a diverge and embrace an india rubber annulus e which by a reduced flange portion is clamped between the outer portions of the discs a. The distance blocks 0, which are of triangular or other section, shown in Fig. 8, pass through apertures in the clamped reduced portion of the rubber annulus e.

The rubber annulus e is moulded with an annularcavity j, which is moulded on to and around the flanges laterally on the inner periphery of a tubular steel hoop. This steel hoop consistsot a pair of annular stamped sheet steel side plates 9 of channel section, interconnected at their outer and inner peripheries by sheet steel hoops h, i to form a hoop of box section, with outwardly laterally directed fianges. Sheet steel hoops y l: are also provided on the inside of the flanges of the plates 1 The plates 9 and sheet steel hoops h, z, j, is are secured together by welding, brazing or the like.

As stated above the rubber annulus c is moulded on to the inner periphery of the tubular steel hoop y it, i, j, l; and around the inner peripheral flanges thereof. To promote the attacl'nnent of the rubber to the metal, metal eyes Z are provided at inter *als around the inwardly directed surface of the inner flanges ot the tubular steel hoop g, 72 '2', j, k, into which eyes Z the rubber interlocks. The rubber also is moulded over the nuts on which retain the stems of the eyes Z in the re-- spective flanges, and into the annular interstices between the components of the flanges.

Mainly to serve as distance pieces for positioning and holding a segmentaljcore bar used tor moulding the cavity in the. rubber annulus 6, but also serving to provide additional means to interlock the tubular steel hoop with the rubber crii'nped. arched steel hoop.

p indicate radial channels moulded in the rubber e for ventilating the cavity 7". I g is a solid rubber tyre moulded on to two *laterallyseparated built-up metal ,bands 1 which are applied around the outer periphery of the tubular steel hoop ,and secured thereto by ,boltss passing through the outer flanges thereof and the borders of the tyre ,bandsm.

'The ,entire wheel constitutes a detachable wheel capable of being mounted by a central aperture on a hub of a vehicle suitable for reception, and on which it is secured by bolts passing through the tubular distance pieces b. l i i r Although ,in the illustrated example the tubular steel hoop is ot box section and the distance blocks 0 are of triangular section, these may'be of other suitable shapes.

I claim: l 'v y 1. A vehicle vwheel comprising two metal discs, a rubber annulus mounted on to the periphery ofsaid discs, a flangedsteel hoop partially embedded in saidrubber annulus, irom which hoop said discs are resiliently suspended, a v plurality of crimped arched metal strips riveted to said hoop on the innerperipheral portionembedded in said rubber annulus, additional interlockin means provided between said hoop and rubber annulus also embedded in same, a band tyre, two laterally separated builtup metalbands moulded thereto being mounted on to the periphery oi'said steelhoop and meansprovided for securing said metal bandstolsaid hoop.

2. A vehicle wheel comprising two metal discs being spaced apart around the hub and near the periphery by distance pieces, the outelgperipheral portions of whichdises diverge, a rubber annulus embraced by-said discs, an annular cavity provided in 'said rubber annulus, a metal ,hoop partially embedded in said rubber annulus, ,flang'es integral with said hoop, a plurality of .crimped arched metal strips securedto said metal hoop and embedded in said annulus, iadditional interlocking means provided be- 1 and securedthereto, an annular cavity provided in said rubber annulus, a metal hoop m jt y em edde in said annulus, in pl rality er crimped arched metal stiips secured to the inner peripheral portion of said hoop, flanges integral with said metal hoop arranged on the inner and outer peripheral portions, a plurality of metal eyes attached to said inner flanges, the latter, thejmetal eyes and cr'imped arched metal'strips embedded in said rubber annulus, twolaterally sepa ated uilt-up metal bendaa band vtrite moulded thereto, said tyre mounted to the pe iphery of said hoop, said metalihands be ngsecuredto the outer peripheral flanges to said inner flanges the latter, the metal 7 eyes and crimped arched metal strips cpl-- beddedin said rubber annulus, twoflatera separated built-up metal hands, a band tyre moulded thereto, said tyre mounted ,on to the periphery of said metal hoop, Said metal vbands being secured tolthe outer ,pen'i pheral flanges of said hoop by bolts. 7
